Re: [Ifeffit] Fe K edge spectrum of scorodite

Thanks! May I add it to the ALS 10.3.2 reference collection? What is the standard of energy calibration? Is the Fe metal edge at 7110.75eV, 7112eV or what? mam On 7/6/2015 7:11 AM, Case Van Genuchten wrote:

Dear Shaofeng,

I am attaching the averaged, raw data and Fe K-edge EXAFS spectrum (extracted using SixPack) of scorodite. The mineral was prepared following the procedure outlined in Paktunc et al. (2008). The data were collected at the Stanford Synchrotron Radiation Lightsource in transmission mode with the sample housed in a liquid nitrogen cryostat. You can find additional details on the preparation of the sample and data collection from the publication where the spectrum is reported and modeled (van Genuchten et al. 2014, Geochimica et Cosmochimica Acta).

Please let me know if you have any other questions about data collection.

Best,
